Okay so I'll try make this short and sweet. I was speaking to this girl,let's call her k, we were getting on really well and I suggested we went for a coffee to better know each other,she said yes and we met up and everything went great, we got on like a house on fire.after that day though she never bothers to message me or get in touch, I didn't let it bother me and moved on.some time later I was speaking to this other girl , I'll call her E, she was being nice to me and rather flirty and vey complimentary, I don't usually take bate like that but I let my guard down. She suggested we met up and again.... Go for a coffee, I was surprised that I was asked and thought she must of been interested.so we met up after she finished college and she mentioned about meeting one her friends who owed her money and that they didn't show so she didn't have the money for a coffee, me being the nice useable guy I am offered to pay with little hesitation.so we had a great chat and all went well, she was friendly and all that.anyways I seen it that she got on her bus and left. Later on that night I told her that I had a good time and it was fun,she respond with "yes it was,thank you" , I asked her why she said thanks and she said for cheering her up! It was at the moment I felt used and confused! I carried on the nice guy persona and she just won't text me unless I text her first. Then out of the blue about 3 days later she got in a relationship.......where did I go wrong? Am I too nice? I really don't know :/ I could do with help because again I'm going on another coffee thing and don't want to make the same mistake a third time in a row. Any feedback would be appreciated.
